Question

Calculate Lead Time Flint Fabricators Inc. machines metal parts for the automotive industry. Under the traditional manufacturing approach, the parts are machined through two processes: milling and finishing. Parts are produced in batch sizes of 85 parts. A part requires S minutes in milling and 9 minutes in finishing. The move time between the two operations for a complete batch is 10 minutes. Under the lean philosophy, the part is produced in a cell that includes both the milling and finishing operations. The operating time is unchanged; however, the batch size is reduced to 3 parts and the move time is eliminated. Determine the value-added, non-value-added, and total lead times, and the value-added ratio under the traditional and lean manufacturing methods. If required, round percentages to one decimal place Traditional Philosophy Lean Manufacturing Philosophy 14 min 14min ×min Value-added time Non-value-added time Total lead time Value-added ratio (as a percent)

Explanation / Answer

Particualars Traditional Lean Manufacturing Value added time 14 14 Non Value Added 0.118 0.000 Total Lead time 14.118 14.000 Value added Ratio (%) 99.17% 100.00%
